Avalanche Activity

The fresh wind slabs will be deposited on surface hoar. Weak layers in the old snowpack necessitate caution.

The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack on west to north to east facing aspects. These can be released easily. or in isolated cases naturally,. Avalanches can release the weakly bonded old snow as well and reach medium size. Caution is to be exercised in particular on wind-loaded slopes, as well as in gullies and bowls, and behind abrupt changes in the terrain above the tree line. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.

Snowpack Structure

Up to 10 cm of snow will fall. As a consequence of a storm force southerly wind, wind slabs will form. These will be deposited on surface hoar especially on wind-protected shady slopes. The old snowpack is faceted and weak.

Tendency

The avalanche conditions remain unfavourable. As a consequence of new snow and wind the wind slabs will increase in size. The weather report and anticipated change in the avalanche danger are uncertain.
